Page 1 of 9 Name: Period: Chapter 2 DESCRIBING MOTION: KINEMATICS IN ONE DIMENSION (17 Problems) Complete problems below. SOLVE ALGEBRAICALLY first - then substitute in numbers on this paper - then plug into calculator ... (college board rubric) Write down 5-8 digits from your calculator Include units Vo = initial v = velocity at a Vavg = average d = displacement from origin = (x-Xo) velocity later time velocity (v2-v1) d(total) d = Vat + 1/2 at v = vo + 2ad v (t) = Vo + at avg At Vavg t(total) Do NOT use v = d/t Vavg=1/2 (v1+v2) only if time Do NOT use speed = distance/time is same for both speeds #1. You are driving home steadily at 65 mph for 130 #2. A complete round trip has the outgoing 200km miles. It then begins to rain and you slow to 55 mph. covered at 90km/h, followed by a one-hour lunch You arrive home after driving 3 hours and 20 break, and the return 200km is covered at 50 km/h. minutes. (203, 61) (55km/h, 0) Enter "givens " into table. out lunch return Total Part 1 Part 2 Total a 0 0 0 0 a 0 0 Vo Vo 008 180 A V inS S) .Bidop ax ox t Check which you pick for your coordinate system a) Complete the table. (go ahead and substitute Out is positive zero acceleration before using algebra) Return is positive a) Fill in the above table (show math for anything not given) leoos ell saw tartW b) Using the table values: how far were you originally from home? (you do NOT need to do more math) b) Average velocity of complete round trip c) What was your average speed
